I am also reasearching casual games at the moment. Ive found a lot of articles about it from a year or so ago.

Is the market still quite 'hot'or cooling rapidly? I like the idea of the fact that casual games take a lot less time to make than big 3d games but still have good potential for earning while allowing for good ideas and creativity.

What is happening with Actionscript 3 and papervision 3d/sandy is really promising I feel for this market.....
